EnableHistoryInfo
[Enable History-Info Header]
Enables usage of the History-Info header.
Valid options include:
0 = Disable (default)
1 = Enable
UAC Behavior:
Initial request: The History-Info header is equal to the Request URI. If a
PSTN Redirect number is received, it is added as an additional
History-Info header with an appropriate reason.
Upon receiving the final failure response, the gateway copies the
History-Info as is, adds the reason of the failure response to the last
entry, and concatenates a new destination to it (if an additional request
is sent).
The order of the reasons is as follows:
- Q.850 Reason
- SIP Reason
- SIP Response code
Upon receiving the final (success or failure) response, the gateway
searches for a Redirect reason in the History-Info (that is, 3xx/4xx SIP
Reason). If found, it is passed to ISDN, according to the following
table:
SIP Reason Code
ISDN Redirecting Reason
302 – Moved Temporarily
Call Forward Universal (CFU)
408 – Request Timeout
480 – Temporarily
Unavailable
487 – Request Terminated
Call Forward No Answer (CFNA)
486 – Busy Here
600 – Busy Everywhere
Call Forward Busy (CFB)
If history reason is a Q.850 reason, it is translated to the SIP reason
(according to the SIP-ISDN tables) and then to ISDN Redirect reason
according to the table above.
UAS Behavior:
History-Info is sent in the final response only.
Upon receiving a request with History-Info, the UAS checks the policy
in the request. If 'session', 'header', or 'history' policy tag is found, the
(final) response is sent without History-Info. Otherwise, it is copied
from the request.
SIPSubject
[Subject]
Defines the value of the Subject header in outgoing INVITE messages. If
not specified, the Subject header isn’t included (default).
The maximum length of the subject is limited to 50 characters.
